Set unlimited proxy allowance error



I am getting an error when I try to set unlimited proxy allowance to an account (setUnlimitedProxyAllowanceAsync)

I use a MnemonicWalletSubprovider, for the first account (path 0/0) it works perfectly, however when I try with the second account (path 0/1), im getting this: Thrown: [object Object]

Any idea about it?

Thank you!
